背景：尽管肥胖率很低，但许多大学生认为自己超重，尤其是女性。这是令人担忧的，因为不适当的体重观念会导致不健康的行为，包括饮食失调。方法：我们使用的数据库从跨国家学生健康调查（CNSHS），包括5,900记录的大学生从保加利亚，丹麦，德国，立陶宛，波兰，西班牙和土耳其分析差异的基础上感知体重状态的问题：“你认为自己太瘦了，有点太瘦了，正好，有点太胖了还是太胖了？".感知体重和身体质量指数（BMI）之间的关联进行了评估，从自我报告的体重和身高的广义非参数回归R库gam.Results：虽然大多数学生报告的BMI正常（72-84%的男性，65-83%的女性），只有32%至68%的学生认为他们的体重“刚刚好”。BMI为20 kg/m（2）的女性中约有20%认为自己“有点太胖”或“太胖”，BMI为22.5 kg/m（2）的女性中这一比例增加到60%。体重指数低于22.5 kg/m2的男生很少感觉“有点太胖”或“太胖”，但体重指数为20 kg/m2的男生大多感觉太瘦。结论：欧洲国家的体重理想相当一致，体重指数正常的女生更容易认为自己“太胖”，而男生更容易认为自己“太瘦”。防止不健康行为以达到不明智的体重理想的计划可能会使学生受益。
Background: Despite low rates of obesity, many university students perceive themselves as overweight, especially women. This is of concern, because inappropriate weight perceptions can lead to unhealthy behaviours including eating disorders.Methods: We used the database from the Cross National Student Health Survey (CNSHS), consisting of 5,900 records of university students from Bulgaria, Denmark, Germany, Lithuania, Poland, Spain and Turkey to analyse differences in perceived weight status based on the question: "Do you consider yourself much too thin, a little too thin, just right, a little too fat or much too fat?". The association between perceived weight and body mass index (BMI) calculated from self-reported weight and height was assessed with generalized non-parametric regression in R library gam.Results: Although the majority of students reported a normal BMI (72-84% of males, 65-83% of females), only 32% to 68% of students considered their weight "just right". Around 20% of females with BMI of 20 kg/m(2) considered themselves "a little too fat" or "too fat", and the percentages increased to 60% for a BMI of 22.5 kg/m(2). Male students rarely felt "a little too fat" or "too fat" below BMI of 22.5 kg/m(2), but most felt too thin with a BMI of 20 kg/m(2).Conclusions: Weight ideals are rather uniform across the European countries, with female students being more likely to perceive themselves as "too fat" at a normal BMI, while male students being more likely to perceive themselves as "too thin". Programs to prevent unhealthy behaviours to achieve ill-advised weight ideals may benefit students.
